My 2wd is posi trac. I did at least make sure of that when i bought. I had good luck last week on the ramp. However I still Have the extra weight in the bed of the truck. I think im getting closer on the trailer adjustment. Maybe i can get by a little longer till i find the right 4x4. I will try about 500# next trip and see how she does.

prob is he would suck the air out of the tires thru the valve stems:eek::evilb:
